Chiral and other non‑centrosymmetric materials host a wide range of novel electronic and magnetic phenomena. Coherent X‑ray beams carrying orbital angular momentum (OAM) offer a new and largely unexplored route for probing these systems, with the potential to access symmetry and dynamical information that conventional techniques overlook. By highlighting recent studies of skyrmion lattice...
Square artificial spin-ices (ASI) with topological defects are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigation of ASI with even-charge topological defects showed both charge and magnetic X-ray scattering yield photon OAM confined to integer OAM values. Here we show that square ASI’s with an antiferromagnetic ground state yield fractional OAM...
